The ongoing heat wave poses risks for heat-related illnesses, particularly for vulnerable populations such as the elderly, children, and those without access to air conditioning. Urban areas, where temperatures remain higher overnight, are especially at risk. The D.C. government has activated its first Heat Alert of the season, offering free transportation to cooling centers. Additionally, the late-week cold front may bring thunderstorms, which could lead to localized flooding or wind damage. Residents are advised to stay hydrated, limit outdoor activities during peak heat, and monitor weather updates for potential storm impacts.
